Detailed explanation-1: -As the Earth revolves around the Sun, the patterns of the stars appear to move. Explanation: The Earth completes its orbit around the Sun or its revolution in about 365 days total. As the Earth revolves around the Sun, the position of the Earth changes and this creates the different views of the night sky.
Detailed explanation-2: -Because circumpolar constellations never rise or set, they provide reliable reference points for astronavigation. Knowing the circumpolar constellations in each hemisphere allows navigators to find their way using only the stars.
Detailed explanation-3: -The constellations you can see at night depend on the time of year. Earth orbits around the Sun once each year. Our view into space through the night sky changes as we orbit. So, the night sky looks slightly different each night because Earth is in a different spot in its orbit.
